After evaporation of the solvent, the product leaves an ultra-thin greasy protective film.Rustilo DW 300 X rapidly removes water from components after electroplating processes, machining with a soluble cutting fluid, or from parts that have been washed. The product can displace water from very intricate assemblies and components. The very thin residual film provides effective short to medium term protection against corrosion during intermediate storage or transportation.
